Rowell Syndrome is a rare presentation of lupus erythematosus manifesting as an eruption of erythema multiforme-like papules and plaques with immunological findings of positive rheumatoid factor, speckled antinuclear antibodies, and/or anti-Ro/La antibodies. This case highlights the unusual and highly debated presentation of Rowell Syndrome in a 66-year-old woman with newly-appearing erythematous, targetoid plaques in the setting of previously diagnosed systemic lupus erythematosus. Skin biopsy revealed histological features of full-thickness epidermal necrosis with focal sub-epidermal separation and a superficial perivascular lymphocytic infiltrate interpreted to favor Rowell Syndrome given her clinical history and presentation. Although no standard treatment exists, a prednisone taper and topical corticosteroids proved effective initially, with complete resolution at six months on mycophenolate mofetil and belimumab.Epidermolytic acanthomas (EA) are rare benign tumors of unclear etiology that present as flat, sometimes slightly keratotic, pale or whitish papules that are usually asymptomatic. Not uncommonly, their clinical appearance in the anogenital area might lead to misdiagnosis as other lesions that commonly develop at this site, such as condylomata acuminata. Though mainly asymptomatic, there are also reports of EA presenting with persistent genital pruritus. We describe the first reported case of pruritic scrotal EA successfully treated with topical pimecrolimus.Epidermodysplasia verruciformis is a rare genodermatosis associated with mutations in the EVER1/TMC6 and EVER2/TMC8 genes. The inheritance is considered to be autosomal recessive, but reports suggesting an autosomal dominant inheritance indicate disease genetic heterogeneity. Its onset occurs in early childhood and presents as a combination of pityriasis versicolor-like, flat wart-like and seborrheic keratosis-like lesions, with a potential for malignant transformation, mainly squamous cell carcinoma.Erythrodermic psoriasis is a relatively rare, more dangerous inflammatory variant of psoriasis associated with high morbidity and mortality. It can be exceptionally challenging to manage, defeating even the most experienced dermatologist's arsenal of treatment strategies. Goeckerman therapy, a regimen of ultraviolet B phototherapy and crude coal tar, has demonstrable efficacy in severe and recalcitrant plaque-type psoriasis. However, its utility in erythrodermic psoriasis has not been explored within the dermatology literature. Herein, we present a patient with a long-standing history of erythrodermic psoriasis refractory to eleven treatment modalities including four biologic agents, who had his erythroderma 'turned around' following Goeckerman therapy. 'Turned around' is used to describe dramatically reducing a patient's cutaneous inflammation so that previously recalcitrant disease can now respond to maintenance therapy. The importance of a one to three week 'cool down' period of topical corticosteroid therapy prior to phototherapy or crude coal tar use is highlighted in this case as well. Although Goeckerman therapy is no longer regularly used, it remains one of the most efficacious treatments available for intractable psoriasis, attracting patients from all over the country desperate for symptom relief. This case suggests it may be useful in 'turning around' extremely difficult-to-treat erythrodermic psoriasis as well.Loose anagen syndrome (LAS) is a hair disorder involving insufficient anchoring of the hair follicle to the scalp owing to an autosomal dominant or sporadic mutation in the gene encoding keratin 6. There are three phenotypes of LAS, including type B, which presents in young, light-haired girls as unruly, uncombable hair with diminished growth. https://www.selleckchem.com/products/apr-246-prima-1met.html We present a 2-year-old girl with LAS type B whose identical twin sister was unaffected. The diagnosis was confirmed with a painless hair pull test proven to contain anagen hairs with ruffled cuticles on trichoscopy, preventing the need for unnecessary referrals and diagnostic tests.Gefitinib is a selective tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR) used for the treatment of malignant neoplasms. The most frequent skin complication during gefitinib therapy is an acneiform papulopustular eruption, usually distributed in the seborrheic areas but occasionally widespread. We report a patient with erosive pustular dermatosis of the scalp, a neutrophil-mediated skin disease presenting with sterile pustules evolving into erosions and crusts on the scalp, during treatment with the EGFR inhibitor gefitinib for lung cancer. A literature review of the drug-induced cases of this rare entity is provided.Progressive nodular histiocytosis (PNH) is a rare type of non-Langerhans cell histiocytosis of the xanthogranuloma group. Less than 20 cases have been reported. We report here a novel case of PNH with dermoscopic description and post-surgical outcome. Our patient presented with pruritic papules and nodules with progression over two years. Dermoscopic examination of large lesions showed multiple telangiectases without ulceration. There was no mucosal involvement. Histopathological analysis of a papule showed a dermal infiltrate composed of histiocytes and many Touton giant cells; a nodule revealed a dermis occupied by spindle cells arranged in a storiform pattern. The nodules were resected and the largest surgical defect, on the forehead, was corrected with A-T advancement flap. The papules were treated with cryosurgery achieving adequate cosmetic outcome without recurrence.The fields of dermatology and psychiatry have overlap in the patient populations and diseases they treat. However, there are not currently fellowship opportunities for dermatologists or psychiatrists specifically interested in gaining expertise in psychodermatology. We discuss the logistics of a one-year psychodermatology fellowship, open to residents after completing either dermatology or psychiatry residencies, and the potential benefits that it could bring to both dermatology and psychiatry training programs across the county.Many patients struggle with choosing and adhering to biologics. Psychological approaches (e.g. decoy effect) may impact patients' choices when selecting a biologic.
Assess whether decoy options influence choice between injectable treatment options.
Following IRB approval, 750 subjects &amp;gt;18 years were recruited through MTurk. Subjects were randomized in a 111 ratio into the following groups 1) baseline comparison between a more effective, weekly injection and a less effective, every-three-month injection; 2) baseline with a decoy inferior to the weekly injection; 3) baseline with a decoy inferior to the every-three-month injection. Treatment preference was self-reported and compared using chi-square tests.
Sixty-six percent of subjects preferred the weekly injection versus 34% for the every-three-month injection (group 1). There was a 4% increase in the number of subjects who preferred the weekly injection (70%; group 2; P=0.34) and a 3% increase for the every-three-month injection (37%) when a decoy inferior to them was included (group 3; P=0.
